BARNS: 
I would like to make some comments on the discussion aDout 
6IS-L1S systems. There is a shortage of low cost GIS-LIS systems. 
There is a system which costs $85, called OSU-map for the PC 
educational CIS within everyones reach, in the US any software which 
is developed in a public domain is often free, one pays only the cost or 
the disk to aquire it and there are a few GIS systems not the best but 
good for education. 
I would like to say something else too which comes out 
through my experience from a land information management 
programme in Ohio State. It's that we have to come back to the 
teaching of fundamentals. It dosn't matter what facts we are teaching, 
we have to teach the students to think critically.

Mr. President, 
Mr Secretery General of Research and Technology, 
Mr President of the Hellenic Organization for Cadastral and 
Mapping, 
Mr President of the International Society for 
Photogrammetry, 
panel members, distinguished collegues, 
it was really a privilege and a great pleasure for me, for the 
Greek Society of Photogrammetry and for the Organising Committee to 
have you here and to share with you the work of this Symposium. Your 
presence ano participation has considerably strengthend the 
performance of this Symposium and of our Commission. I am sure that 
most of the participants have noticed the improvement of the 
activities of Com. V|_ which was nicely pointed out by prf. Konecny, but 
also the structural problem of the Commission that still persist. I can 
assure you that myself, the Commission Secretary Dr. Georgopoulos and 
the members of the Com board have tried as hard as possible to 
promote the activities of our Commission. It will require however 
much more time and considerable additional efforts until the 
performance and the importance of Com. VI will reach a level 
comparable with the levels of the other technical commissions of 
ISPRS. We hope that at the 1992 Congress in Washington the 
improvements will become much more obvious ana the structural 
problems will further diminish. As i have said in my welcoming speech 
we have tried to make the Symposium important, fruitful and pleasant.
